Sampling
Sampling is defined as a researcher selecting a small set of cases from
a large pool and generalising to the population (Newman, 2011). The
sample should be a representation of a population to enable
generalisations about the population (ibid.).
In non-probability sampling there is a limited knowledge about the
research population (Newman, 2011). A non-probability sample technique
(haphazard sampling) was used, because our case studies have the same
characteristics (they are all IT academic students at the Department of
IT at CPUT Cape Town campus). The sampling frame involved students of
each domain within the Department of IT at CPUT, the domains are as
follows:
- Foundations domain
- Undergraduate domain
- Graduate Domain
- Post graduate Domain
